Nearly 20 quantum computing companies have been chosen to enter the initial stage of DARPA’s Quantum Benchmarking Initiative (QBI), in which they will characterize their unique concepts for creating a useful, fault-tolerant quantum computer within a decade.

The Taiwan Semiconductor Research Institute (TSRI) under the National Applied Research Laboratories today announces the procurement of its first full-stack quantum computer from IQM Quantum Computers (IQM), a global leader in designing, building, and selling superconducting quantum computers. The delivery and installation of the system at TSRI’s premises will take place in the second quarter of 2025.

Today, Nature published an Intel research paper, “Probing single electrons across 300-mm spin qubit wafers,” demonstrating state-of-the-art uniformity, fidelity and measurement statistics of spin qubits. The industry-leading research opens the door for the mass production and continued scaling of silicon-based quantum processors, all of which are requirements for building a fault-tolerant quantum computer.

Researchers from Fujitsu and QuTech have developed new and ultra-cold electronic circuits to control diamond-based quantum bits. As a result of their joint research project, it becomes possible to build larger quantum computers, through overcoming the ‘wiring bottleneck’, while maintaining high quality performance. In fact, both the quantum bits and the control electronics can be conveniently operated in a single compact cryogenic refrigerator. The researchers publish their results at IEEE’s ISSCC.

HPE team selected by DARPA to assess feasibility, development, and benchmarking of utility-scale quantum computers.

Diraq today announced that it was awarded a Stage A contract with the Defense Advanced Research Projects Agency (DARPA) to work on its recently announced Quantum Benchmarking Initiative (QBI). This initiative, led by the US Government, seeks to determine whether it’s possible to build an industrially useful quantum computer much faster than conventional predictions. It represents a tangible investment by the US Government in progress toward realizing the promise of commercially viable quantum computing systems.

Now, researchers from the Harvard John A. Paulson School of Engineering and Applied Sciences (SEAS), in collaboration with Stanford University and the University of California – Berkeley, have developed an on-chip twisted moiré photonic crystal sensor that uses MEMS technology to control the gap and angle between the crystal layers in real time. The sensor can detect and collect detailed polarization and wavelength information simultaneously.

Lightmatter has announced Passage M1000, a groundbreaking 3D Photonic Superchip designed for next-generation XPUs and switches. The Passage M1000 enables a record-breaking 114 Tbps total optical bandwidth for the most demanding AI infrastructure applications.

Nanofiber Quantum Technologies, Inc. (NanoQT), a pioneering quantum hardware startup, has opened a new office in College Park, Maryland to strengthen its research and development capabilities and accelerate its commercialization efforts in the United States.
